If you upload oricutron videos direct to YouTube, they often turn into an overcompressed mess, although it seems to depend slightly on the device you use to play it back. There is a thread on here describing how to pass the video through ffmpeg first for better results.

Just a quick additional note, if you change the "scale=720:672:flags=neighbor" parameter to "scale=960:672:flags=neighbor", you'll also give the video a bit of a horizontal stretch and make it look closer to the aspect ratio of a real Oric:

Several people have found that if you upload Oricutron video captures direct to youtube, it re-encodes them into a crappy mess, even though the original video was losslessly encoded (and thus pixel perfect). The issue is that the videos are low resolution (240x224), so youtube encodes them with low ...

That mean that Dos-8D will never work if someone replace the 6502 with a CMOS version, clever! Depends on the instructions used. Some are the same on 65c02. The Apple II users learn that the hard way when Apple switched (and some user too) from the NMOS 6502 to the CMOS 65C02 version. But the Oric ...

Hmmm... according to the documents I could find online, opcode 04 is essentially a "nop", but it should consume an immediate operand. Looking at the code, I made it count the cycles correctly, but not consume the operand. No need for a message box. If you make all the "DOP" instructions add 1 to PC,...
